PIG-MENT-STIRBING- PAN.

Application filed May 16,

To all whom it may concern:

Be it known that 1, CHARLES P. Bossnnr, a citizen of the United States, residing in the city and county of lllilwaukee, State of lVisconsin, have invented a new and useful Pigment-Stirring Pan, of which the following isa specification.

In the art of treating or manufacturing leather, there are certain grades or classes of skins, which at certain stages of their manufacture require the application thereto of a suitable pigment, which is applied by hand, and which liquid or pigmentis of such a nature that it requires constant'stirring or agitation so that the ingredients thereof may be at all times properly commingled.

The object of my present invention is to effect this pigment stirring operation by automatic, mechanical means which require no attention on the part of the operator, my novel device in its entirety being readily supported upon a. .work, bench occupying very little room, and requiring no attention on the part of the operator other than the replenishing of the pan with pigment according to requirements, and the adjustment or manipulation of the valve, which controls the inlet of the motive fluid which rotates the pan of pigment with respect to the stationary stirring device.

To the above ends my invention consists of a novel construction of a pigment stirring pan, comprising an outer casing, a table or support rotatably mounted therein and provided on its bottom surface with an annular series of buckets, which are adapted to receive the impact of the motive fluid, which is introduced tangentially into said casing against said buckets, provision being also made for supporting the pigment stirring blade in relatively stationary position and locking the same from movementwith respect to the pigment containing pan and its adjuncts, whereby the pigment will be mechanically and automatically stirred or agitated without any, attention on the part of the operator.

To the above ends my invention consists ofa novel construction of a pigment stirring pan and its adjuncts, the novel features of which will be hereinafter fully set forth and pointed out in the claims.

For the purposeof illustrating my invention, I have shown in the accompanying Specification of Letters Patent.

drawings a form thereof which is at present preferred by me, since it will give in practice satisfactory and reliable results, although it is to be understood that the various 'instriunentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described.

Figure 1 represents a perspective View of my novel construction of pigment stirring pan, and its adjuncts.

F gure 2 represents on an enlarged scale, a. plan view of the pan and its adjuncts seen 111 Figure 1, a portion of the outer casing being broken away to show the tangentially disposed nozzle for the incoming motive fluid.

1 designates my novel construction of pigment stirring pan, and its adjuncts, the same comprising the pan 2, which is positioned within the vertical flange or lip 3 of the rotary table t, the bottom of which is provided with the annular row of buckets 5, collocatec'l as will be understood from Figure 2, and positioned inthe path of the incoming jet of water or other liquid or fluid introduced or conveyed under pressure to the tangentially arranged nozzle 6, through the inlet pipe 7, which has the control valve 8 therein. The rotary table a has a central bottom hub 9, from which depends the vertical stem 10, whose lower end may be pointed and stepped into the hardened bearing 11 which is screwed into the bot-tom of the tubular extension 12 by the polygonal head 14:, which has the flange 15 abutting against the bot tom of said extension. The casing 13 is composed of the base portion 16 and the vertical outer annular wall of flange 17, at the inner upper portion of which is located the inwardly projecting annular ledge 18, which is provided with the holes 19, said ledge preventing the motive fluid from splashing upwardly. The vertical stem 10 is guided by any suitable ball bearing device 20, contained in the seat 21, it being understood that any conventional type of ball bearing indicate valve.

may be employed, to take up the side thrust.

22 designates a port in the base 16 of the casing 13, which is preferably counterbored, as will beunderstood from Figure 4, below which port is positioned the exhaust or outlet pipe 23, the upper end 24 of the latter being preferably tapered, as will be understood from Figure 4.

25 designates a lug on the side of the casing 13 having a vertical hole 26 therethrough, in which is seated the head 27 of the arm or bracket 28, which is composed of the members 29 and 30, the latter having secured thereto the blade or stirrer 31, whose bottom. edge34 is raised a short distance from the bottom of the pan The top of the lug 25 has the transverse seat 32 therein, see Figure 2, which receives the ends of the transverse pin 33, which passes through the bottom head 27, as will be understoodfrom the rightofFigLn-e 2, wherefrom it will be seen that the arm 28 and the stirrer or blade 31 are readily dropped into position and are held relatively stationary to the rotary pan 2, and rotary table 4. The casing 13 may be of cast iron and the rotary table 4 of cast iron and bracket 28 of brass.

In Figure 1, I have shown my novel device as ready for use upon the bench 35, and in proximity-to the work slab 86.

, 37 designates an annular groove in the outer periphery of the rotary table 4.

The operation is as follows LThe pan 2 is filled to the desired extent with the pigment or other liquid and the stirrer or blade 31 assembled with respect thereto, so that the parts appear as best seen in Figure 2. The operator then opens the valve 8 and the water or other liquid or fluid under pressureenters the nozzle 6, (see Figure 2) and impinges or impacts upon the buckets 5 whereupon the table 4 and the pan 2 revolve in unison, the speed of rotation being controlled by the manipulation of said The blade, 31 being relatively stationary effects the desired stirring of the pigment or other liquid, and the exhaust liquid ,escapes through the outlet pipe 23. By the provision of the ball bearings 20 and the stepped bearing 11, friction is reduced to a minimum and any dripping or splashing from the pigment containing pa11 2,-can flow through the ports 19 to the bottom 16 of the casing 13;

, It will be understood that the weight of the pan and its contents and adjuncts issupported on the pointed end of the stem 10 resting on the step bearing 11, there being a' tion, and while I have, in the present instance shown and described a preferred embodiment thereof which will give in practice satisfactory and reliable results it is to be understood that such embodiment is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages. I
